Dash cam video showed Custer County sheriff's deputies taking more than $400,000 worth of drugs off the streets in a bust.
A routine traffic stop near Weatherford led officials to the 85 pounds of marijuana.
Authorities said they found so much marijuana they had to take it to the post office to weigh it all.
"I believe they got it from Colorado just based on some of the evidence that we were able to collect inside the vehicle," Deputy Dillon Mach with the Custer County Sheriff's Office.
And they were headed to Tulsa with it, but were stopped on I-40 in Custer County, authorities said.
During the traffic stop, deputies brought out their drug dog. And he immediately alerted them to something in the back of the minivan.
They found loads of marijuana stuffed into duffel bags. It was hydroponic marijuana, meaning it was grown inside and has a higher THC level, which means it's got a higher street value.
Authorities took Paul Carrao, Aubrey Skelly and Terri Skelly into custody.
All three are from the Tulsa area and wouldn't admit much, deputies said. But what they were up to wasn't really a surprise to deputies.
"Probably once a week, if not more, we stop cars on the interstate that are coming from Colorado, and they went there to legally buy marijuana."
Everyone was taken into custody along with their 85 pounds of pot and $19,000 of cash.
All three could face up to 25 years for trafficking drugs and up to life if they've got prior convictions.
